High compactness stereoscopic filtration thickened mask

Abstract

The invention relates to a high compactness stereoscopic filtration thickened mask, which comprises a mask body (1). Two belts (2) are hung on the two sides of the mask body. The mask body comprises a gauze layer (1.1), a filter layer (1.2) and a cotton layer (1.3). A support cover (3) is disposed in the middle of the mask (1). The shape of the support cover is matched with the shape of a nose. The binding edge (4) is disposed in the outside of the mask body. The mask body comprises three layer constructions with good breathability and hygroscopicity. The mask can filter the dust and germs among the air. The mask body, the outline of a nose and a face combine closely, which isolates the outside virus and bacteria effectively and stop the steam of the mouth from obscuring doctors' lens.

Description

Technical field [0001] The invention relates to a mask, in particular to a three-dimensional filter thickened mask with a high fit degree. Background technique [0002] Existing masks are generally composed of masks and straps. When they are buckled on the nose and mouth, due to the bulge of the nose, the joints between the mask and the nose and the face are not tightly closed, forming an air channel, which is used for medical and epidemic prevention. In the protection function, viruses and bacteria can easily enter through this channel, which does not meet the requirements of isolating viruses and bacteria. Summary of the invention [0003] The purpose of the present invention is to overcome the above-mentioned shortcomings and provide a high-fitting three-dimensional filtering thickened mask, which can make the mask body closely integrate with the contour of the nose and the face, and effectively isolate external viruses and bacteria. [0004] The object of the present invention ...

AI Technical Summary

Problems solved by technology

[0002] Existing masks generally consist of a cover and a lanyard. When it is buckled at the mouth and nose, due to the bulge of the nose, the joint between the cover and the contour of the nose and the face is not tightly closed, forming an air passage. When protecting, viruses and bacteria can easily enter through this channel, which cannot meet the requirements of isolating viruses and bacteria
